In an opinion column at the Washington Post, George Washington University law professor Jonathan Turley discussing how the United States’ expanding security powers can affect individual privacy and liberties:

Every year, the State Department issues reports on individual rights in other countries, monitoring the passage of restrictive laws and regulations around the world. Iran, for example, has been criticized for denying fair public trials and limiting privacy, while Russia has been taken to task for undermining due process. Other countries have been condemned for the use of secret evidence and torture.

Even as we pass judgment on countries we consider unfree, Americans remain confident that any definition of a free nation must include their own — the land of free. Yet, the laws and practices of the land should shake that confidence. In the decade since Sept. 11, 2001, this country has comprehensively reduced civil liberties in the name of an expanded security state. The most recent example of this was the National Defense Authorization Act, signed Dec. 31, which allows for the indefinite detention of citizens. At what point does the reduction of individual rights in our country change how we define ourselves?

While each new national security power Washington has embraced was controversial when enacted, they are often discussed in isolation. But they don’t operate in isolation. They form a mosaic of powers under which our country could be considered, at least in part, authoritarian. Americans often proclaim our nation as a symbol of freedom to the world while dismissing nations such as Cuba and China as categorically unfree. Yet, objectively, we may be only half right. Those countries do lack basic individual rights such as due process, placing them outside any reasonable definition of “free,” but the United States now has much more in common with such regimes than anyone may like to admit. [...]

The list of powers acquired by the U.S. government since 9/11 puts us in rather troubling company.

Assassination of U.S. citizens

President Obama has claimed, as President George W. Bush did before him, the right to order the killing of any citizen considered a terrorist or an abettor of terrorism. Last year, he approved the killing of U.S. citizen Anwar al-Awlaqiand another citizen under this claimed inherent authority. Last month, administration officials affirmed that power, stating that the president can order the assassination of any citizen whom he considers allied with terrorists. (Nations such as Nigeria, Iran and Syria have been routinely criticized for extrajudicial killings of enemies of the state.)

Indefinite detention

Under the law signed last month, terrorism suspects are to be held by the military; the president also has the authority to indefinitely detain citizens accused of terrorism. While the administration claims that this provision only codified existing law, experts widely contest this view, and the administration has opposed efforts to challenge such authority in federal courts. The government continues to claim the right to strip citizens of legal protections based on its sole discretion. (China recently codified a more limited detention law for its citizens, while countries such as Cambodia have been singled out by the United States for “prolonged detention.”) [...]

Warrantless searches

The president may now order warrantless surveillance, including a new capability to force companies and organizations to turn over information on citizens’ finances, communications and associations. Bush acquired this sweeping power under the Patriot Act in 2001, and in 2011, Obama extended the power, including searches of everything from business documents to library records. The government can use “national security letters” to demand, without probable cause, that organizations turn over information on citizens — and order them not to reveal the disclosure to the affected party. (Saudi Arabia and Pakistan operate under laws that allow the government to engage in widespread discretionary surveillance.) [...]

Continual monitoring of citizens

The Obama administration has successfully defended its claim that it can use GPS devices to monitor every move of targeted citizens without securing any court order or review. (Saudi Arabia has installed massive public surveillance systems, while Cuba is notorious for active monitoring of selected citizens.)
